APPARATUS FOR CUTTING CORK snieETs.

To all whom it may concern:

Be it known that I, ALEX BOGDANFFY, a subject of the King of Hungary, and resident of the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Apparatus for Cutting Cork Sheets, of which the following is a specification.

The present invention relatesto machines for cutting or slicing thin sheets or very thin boards from blocks of cork.

The object of the invention is to provide a device of the character specified, whereby the above mentioned operation is effected automatically, after the blocks of'the cork have been attached to the work-holder.

Another object of the invention is to provide a simple, inexpensive and effective means for advancing the blocks a definite distance at predetermined intervals.

A further object of the invention is to provide means, whereby the thickness of the sheets to be cut may be varied according to the requirements.

A still further object of the invention is to provide a grinding device, permanently in contact with the cutter. of the machine,

whereby suchcutter may operate upon the 1 material without the necessity of removing the same from time to time for the purpose Other objects of the invention will be apparent in reading the specification and from an examination of the drawings, forming part of the present application for Letters Patent.'

Broadly speaking, the invention consists of a rotary cuttenoperating upon the cork blocks, which are attached to a rotary and longitudinally movable carrier, the longitudinal movement of which is governed by the speed of the rotary knife or cutter.

The invention is illustrated in. the accompanying drawings, in which.

Figure 1 is an elevation of a machine embodying the invention, Fig. 2 is an end view of the same, Fig. 3 is a section partly in elevation, of the work-holder advancing means, Fig. 4 is a section taken on line 4, 4 of Fig. 3, and Fig. 5 is a detail of construction of the operating mechanism* of the advancing means. Figs. 6, 7 and 8 are details of constructionof the cutter grinding means, and

Fig. 9 is a section taken on line 9, 9 of Fig.

Fi 10 is a detail of construction of the workho der.

In the drawings, a horizontal table or base plate is indicated at 11, supported by a plurality of standards or uprights 12. To this base plate is adju'stably secured a frame 13.

This frame is attached to the base plate b means of bolts 14, 14, engaging the slots 15,

15 of the base plate 11, and sup orts bear-,-

ings 16, 16, in which is journale fixed pulley 18 and a loose pulley 19, for the driving belt, and a pulley 20, from which some of the operating parts of the machine are driven. The driving shaft 17 is prevented from longitudinal movement by having the portion, journaled in the bearing 16, made conical and being in screw-threaded engagement with rings 21, 21,, contacting with the bearing-block. p

A disk cutter or knife 22 is arranged This knife is kept constantly incontact with the grinding wheels 23, 2 1 and 25, which sharpen the cutters continuously, and allo' thus of a continuous working without the necessity of removing from time to time the cuttor for said purpose. More particularly, the grinding wheel 23 is arranged on a spindle 26, j ournaled .in a frame 27, having a dove-tailed plate 28, in engagement with a supporting late 29, adjustably secured to the frame 13 y means of a screw bolt 30, engaging a slot 31 in the frame 13 and being arranged parallel to the plane of rotation of the cutter 22.

The slot 31 and bolt 3O allows thus of an ad-,

ed upon the spindle 26, and a driving pulley 37, carried by the driving shaft 17. These two pulleys are arranged in planes at right angles to each other, as shown in Fig. 1 of the the driv ing shaft 17 of the machine, which carries, a

spindle 46, adjust-ably carried by a bracket 47, mounted upon the support 42, hereinbeand 54, and driven from the fore mentioned. A spring 49 keeps the grinding wheel in contact with the rotary cut ter22.

The cork blocks 5 0, 50, are secured to a work-holder 51, mounted upon one end of a driven'shaft 52, ournaled in the bearings 53 pulley 55 by means of a belt 56, driving the pullcy 57,

mounted upon the driven shaft 52. f pulley 55 is carried by a eountershaft 58, hav- The ing a-pulley 59 keyed upon the free end there of, the'belt 60 of which engages the pulley 20 of the driving shaft 17, hereinbefore described. A clutch 61, operated by a lever 62,

sects the two sections of the shaft58, which carry the pulleys 55 and 59, res'pec :tively, and allows therebythe shaft 52 to be brought to its condition of rest, although the rot'ation of the driving shaft 17 is maintained.

'40: plate 63, of a cross-like configuration, which The work-holder 5] consists of a base is secured, in the case illustrated in the drawings, by means of a key 64 to the driven shaft 52. To this base late 63 are attached, referably, metal p ates 65, carrying Wooden cards 66. The metal plates 65 are held u on the base plate 63 by'nieans of Y- d clamps 67, having jaws 68, 68, engaging the outer edges of the metal plates 65, and by means of holding plates 69, engaging the inner edgesof the same,-which holding plates are provided with squared bolts 7 0, engaging the square holes of the base platen-5 and the Y-shaped clamps 67, and being held in en agement therewith by nuts 7 l, 7].. Theineta plates 65 and the wooden board 66,-secured thereto, are thus held in position 11 on the Work-holder and rotate therewith. T e cork blocks 50are secured to the wooden boards 66 by pasting the same thereto, preferably, by means of pitch.

. Obviously in rotating the driving and driven shafts, the cutter will operate upon the cork blocks, and slice off sheets, the Work-holder is advanced toward the cutting formed therein, is filled a suitable abrasive substance 44.

The ratchet Wheel is held against longitudinal movementby the bearings 74 80 and 75 and is rotated by means of apawl 80, adjustably carried by a lever 81, arranged upon a rod 82, journalcd in bearings 83 and 84, respectively, which rod may be oscillated by means of a suitably shaped cam 85, car- 85 ried by a collar 86, mounted upon the driving I 52 and participating in the rotation thereof. This cam works against a yoke 87, mounted u )()H the oscillating rod It will be observe from Fi .5 of the drawings, that the cam 85 is provi ed with, slots 88, 88, engaged by screw bolts 89, 89, whereby the relative position of the cam, and collar may be varied according to the requirements. A

hand wheel 90 is mounted upon the free end of the rod 72 for a well known purpose.

In the operation of the machine, the cork blocks, properly prepared, are placed in the manner hereinbefore described upon the work-holder and brought by means of the hand wheel 90 in contact with the cutter The machine being then set in motion, the cutter 22 and the work-holder 51 are rotated. The cam 85, working against the yoke 87,

gives an angular turn to the rod 82, and,

when the yoke is allowed suddenly to be disengaged witli the highest point 85 of the cam and to engage the lowest point S5, the pawl 80 will cause the ratchet wheel to ad- 'vance a predetermined number of degrees,

advancing thus the work-holder a predeterm ned distance, determining thus the thickness of the shoe or sheet. Obviously. (lUllIlQ each revolution of the shaft 52 the ratchet wheel caused to turn aprcdetermincrl number of degrees, and the work-holder to be advanced a distance, which depends upon the relative position of the cam and ring 86.
